Digital BW, The Print

I am using Eboni in the Y, MK and PK positions, PKN in the C,R and B 
positions, PK is spare but has PK in it and Glop is in the Glop 
position.

I managed to get perfect nozzle checks in the positions but a couple 
of failures in the PK and MK positions.  I ran a cleaning cycle and 
lost some more nozzles tried again and the position was worse.  I 
tried again and very few nozzles fired properly.

I waited three hours.  After acouple of nozzle checks, the R, G and 
B were OK so I printed with these using QTR.

The next day I tried again and after two cycles of nozzle checks, 
cleaning and waiting three hours I was able to profile a new paper 
with the PKN inks.

This morning I am back to square 1.  I don't think I have clogs but 
bubbles caused by the aggressive cleaning regimen of this printer.  
Has ay one experienced this problem?  Has anyone resolved it?

Thanks,

Colin

You're probably right that it's air in the outlets.  You might try 
priming the carts to pull the air out.  I use a modified MIS bottom 
fill adapter on a syringe to do this.  See 
http://www.paulroark.com/BW-Info/Modified-Bottom-Fill-Adapter.pdf

Keep an eye out for clogs also.  You have a lot of high load inks in 
that machine along with binder (glossy inks and glop).  If it turns 
out to be a problem, consider a physical arrangement that has a 
cleaning cart between the MK and PK.

Paul,

Thank you for this.  I forgot to menton that I am using a (dis?)
continuous flow system.  I also forgot to shorten the bottom fill 
adaptors.

All the cleaning cycles meant that I ran out of ink.  I reordered 
from MIS but it takes bou ten days to cross the pond.
